A kind of cutting propagation method of distant hybrid Xia Lamei

Abstract

The invention discloses a cutting propagation method of the distant hybrid summer wintersweet. The remote hybrid summer wintersweet is fertilized and managed on the mother plant before cutting; at the same time, the collected cuttings are cut into 5-12 cm cuttings, and the The cuttings are treated with scratching at the base, soaked in sugar water, and soaked in naphthaleneacetic acid before cutting. The present invention effectively manages the fertilization of the mother plant before cutting, so as to obtain more branches that meet the interception conditions before cutting, and at the same time combines the treatment of cuttings with base scratching, sugar water soaking, and rooting liquid soaking to effectively improve rooting survival rate of cutting seedlings.

Description

technical field [0001] The invention relates to the technical field of planting special ornamental trees, in particular to a method for cutting and propagating distant hybrid wintersweet wintersweet. Background technique [0002] Sinocalycanthus chinensis×Calycanthus floridus, a new species of Cesaceae, is a distant hybrid of Sinocalycanthus chinensis×Calycanthus floridus. Wintersweet (Calycanthus floridus) is the male parent, and the intergeneric hybrid was successfully cultivated in 2001 for 7 years by using distant hybridization technology. 2009) and named it "Red Luck". It is a rare flowering and deciduous shrub species with strange flowers, novelty, strong growth potential and good adaptability. It is a new variety of landscaping. It has better prospects for application in landscaping, and the market demand is also increasing. Because the distant hybrid of wintersweet is a distant hybrid, it can bloom but cannot bear fruit and has no seeds. In addition, the number of ...

AI Technical Summary

Problems solved by technology

Because the distant hybrid of wintersweet is a distant hybrid, it can bloom but cannot bear fruit and has no seeds. In addition, the number of seedling mother plants is small at present, so it is impossible to achieve a large number of divisions, and a suitable grafting rootstock has not yet been found. Tissue culture method No progress has been made. Therefore, the breakthrough of the cutting seedling raising method of the distant hybrid wintersweet has become the main way to expand the reproduction rate.

[0003] At the same time, since there is only one successful hybridization of the mother plant of seedlings, the number of cutting seedlings that can be obtained each year is not enough to explore the process parameters of conventional cutting methods, and it is impossible to obtain effective cutting propagation methods to achieve a higher survival rate, so as to expand propagation , so that the cutting propagation of the distant hybrid summer plum has been stagnant
